Regular Schedule or Severe Service Schedule at AutoSurgeonInc?

Today's AutoSurgeonInc article focuses on severe service maintenance. Many Lansing drivers are not aware of them and yet there are also very vocal advocates in Michigan who think that severe service schedules apply to everyone. Somewhere between a complete lack of awareness and the dire blanket statements lies a reasonable approach to severe service maintenance at AutoSurgeonInc.

To back up a little, vehicle owner's manuals have schedules for preventive maintenance: things like oil changes, transmission service and so on. They say you should change your oil after a certain distanced traveled or after so many months. Lansing drivers understand this very well. What they may not know is that there are actually two service schedules: the regular schedule and the severe service schedule. The mileage and time intervals are lower on the severe service schedule.

Now when you hear 'severe service,' you may think it doesn't apply to you because you don't feel your driving conditions are severe or extreme – it's just normal everyday driving in the Lansing area. So let's list some of the conditions that classify as severe so that you can make the judgment on your own driving.

Before we start the list, here's a point of contrast that definitely is not severe driving. Driving down your nearest Michigan interstate at the highway speed limit on a 75 degree F/24 degree C day loaded only with your passengers. This is an easy trip for your vehicle: your engine is loafing along at low RPMs, no heavy loads to pull and moderate Lansing temperatures. Now let's look at some severe service driving conditions.

Most trips around Lansing are less than four miles/six and a half kilometers. When your vehicle engine cools down, moisture condenses in the engine. This water in the oil doesn't get a chance to evaporate on short trips because the oil doesn't get hot enough. A lot of short trips in your vehicle means a lot of water build up. And water in the oil leads to the creation of sludge which can damage the engine. Changing the oil more frequently keeps sludge from building up. By contrast, highway driving warms the engine up and gets the water burned off.

Here's another example. Most trips around Lansing are less than 10 miles/16 km and outside temperatures are below freezing. This is the same reasoning, but in very cold Michigan weather it takes even longer for the oil to get hot enough to evaporate the water, hence 10 miles/16 km as opposed to 4 miles/6.4 km.

Next, you drive in very hot Michigan weather. The hotter it is outside, the more cooling the engine, transmission, brake fluid and so on becomes. The environment in which the fluids reside is more hostile, and the fluids simply break down faster. Therefore, the lower change interval.

Another: driving at low speed most of the time. Every vehicle engine has what's called its power band. This is a range of RPMs in which it's most efficient. Low speed driving doesn't keep the engine in its power band so it's working harder. This is one of the reasons that ratings are worse in downtown than on the highway.

Stop and go driving in Lansing is another severe service condition. You're always accelerating, which works the vehicle engine and transmission harder. Then you're stopping, which works the brake fluid harder, causing it to get very hot. Highway driving, on the other hand, requires far less horsepower to maintain its speed than getting a stationary vehicle from a stop light up to 25 mph/40 kph. A lot of this and you'll need to follow the severe service schedule.

Also on the list is operating your vehicle in dusty, polluted or muddy conditions. Obviously, your engine air filter and cabin air will get dirty faster and need to be changed more frequently as will your breather element. Some of this dust and dirt will make its way into your fluids. They will simple get dirty faster and won't protect the components as well as fresh fluids.

Finally, you're driving under severe conditions in Lansing when you tow a trailer, regularly carry heavy loads or carry a car-top carrier. This is pretty obvious. You'll spend more time in lower gears so the engine and transmission work much harder and create more heat. Brakes will be more stressed stopping the heavier loads.

Sounds like most of us in Lansing operate under severe driving conditions at least some of the time. How can Lansing drivers know which schedule to follow?

Think of it as a spectrum with "always driving under severe conditions" on one end and "never driving under severe conditions" on the other end. Some will be at one extreme or the other, but most of us will fall somewhere in between.

Carefully think about your driving conditions and decide if you should do your preventive maintenance closer to the severe service recommendation or the regular recommendation. Of course, your AutoSurgeonInc service advisor can help you with your decision.

Vehicle tips

According to recent studies, 5 percent of all motor vehicle fatalities are clearly caused by automobile maintenance neglect.

The cooling system should be completely flushed and refilled about every 24 months. The level, condition, and concentration of coolant should be checked. (A 50/50 mix of anti-freeze and water is usually recommended.)

Never remove the radiator cap until the engine has thoroughly cooled. The tightness and condition of drive belts, clamps and hoses should be checked by a pro.

Change your oil and oil filter as specified in your manual, or more often (every 3,000 miles) if you make frequent short jaunts, extended trips with lots of luggage or tow a trailer.

Replace other filters (air, fuel, PCV, etc.) as recommended, or more often in dusty conditions. Get engine drivability problems (hard stops, rough idling, stalling, diminished power, etc.) corrected at a good shop.

A dirty windshield causes eye fatigue and can pose a safety hazard. Replace worn blades and get plenty of windshield washer solvent.

Have your tires rotated about every 5,000 miles. Check tire pressures once a month; let the tires cool down first. Don't forget your spare and be sure your jack is in good condition.

Testimonials

My husband has taken his car to Auto Surgeon for many years and has nothing but praise for their expertise and customer service. We both trust that whatever the problem, we're in good hands with Bill and his team. Today it was my car's turn to need repairs. Within 90 minutes of dropping it off, they contacted me with a diagnosis and an estimate. By early afternoon, my car was ready. First-rate experience, start to finish. No one wants car problems, but if you have them, this is the place to go.-Ginnie P.

Auto Surgeon has been honest with me since I've been bringing my truck and car to them to be serviced. Just last week, I needed my car repaired by the weekend. I took it in on Friday am (major work done) and they had it back to me at 4:30 that afternoon. They take care of you from the time you drop it off until you pick it up. First class all the way! They will be doing work on all my vehicles. Oh yeah, I even stole a pen from Bill. Thanks!!!!-Steven Jacobson

Auto Surgeon guys have always been honest and up front with me. They get the job done and let you know anything else going on trying help you out before it becomes a problem.-Ryan - Lansing, Michigan

I didn't have any actual work done, but they were very honest with me when they took a look at my vehicle and told me exactly what needed to be fixed. There were also priced very fair. I will definitely return in the future!-Matt T. - Lansing, Michigan

Great speed and efficiency on all repairs. Communication between Bill and myself was very quick and he notified me right when my car was fixed. My family returns for multiple reasons. Great service and car care, but overall because Bill is a great business owner and always takes the time to go above and beyond by helping to explain what we can do to maintain good care on my car. Will definitely be returning.-Sam Rathbun - Haslett, Michigan
